The Siberian Ice Maiden Devochka is a mummy of a young Scythian woman from the 5th century BCE, found in 1993 in a kurgan of the Pazyryk culture in Republic of Altai, Russia.
The mummified remains of the “Ice Maiden,” a Scytho-Siberian young woman who lived on the Eurasian Steppes, were found undisturbed in a subterranean burial chamber.
DNA testing confirmed that the Scytho-Siberian maiden was NOT related to present-day peoples of the Altai. It turns out that the maternal line of Devochka the Scythian Ice Maiden is HV2.
HV2 maternal DNA is a very rare haplogroup. It was found in 2 individuals from a Scythian grave site including the spectacularly preserved Ice Maiden Devochka.
Genetic studies showed that the Pazyryks were a part of Samoyedic family, with very strong elements of ancient Iranian-Caucasian substratum.

Today the highest occurrence of HV2 maternal lineage is found in Slovakia in Central Europe and among the Volga Bulgars.
In the Iranian Plateau, HV2 appears either in populations that are native to the Caucasus or Caspian mountain regions and/or to the population groups that originated from the Caspian or Caucasus region and migrated further South and East.
HV2 mtDNA demographics in Study Populations in Iran are as follows:
Persian Central and southern central Iran – 2.4%,
Gilaki Northern Iran, southwestern Caspian Sea area – 8.1%,
Kurdish Western Iran – 5.0%,
Lur Southwestern Iran (Zagros Mountains) – 5.9%,
Baluch South Eastern Iran-western Pakistan, Baluchistan – 10.3%,
Parsi Zoroastrians of Karachi Pakistan- 9.1%,
My maternal grandmother was a Zoroastrian from kerman and as it appears through her, I carry the same EXACT maternal DNA HV2 as the Scythian Ice Maiden.
It appears that the genetic studies show that the ancient Iranians and ancient Zoroastrians directly descend from Indo European populations that lived in Southern Russia, Northern Caucasus and South of Ural Mountains.

Authentic Gatha Zoroastrianism 
fascinating to read this on how “the ancient Iranians and ancient Zoroastrians directly descend from Indo European populations that lived in Southern Russian, Northern Caucasus and South of Ural Mountains.”It appears the princess was covered with some very beautful tattoos

After a recent DNA test, I found out that my maternal Haplogroup is HV2. My maternal grandmother was from the Caucuses while I was born and raised in IRAN. Of course, Iran used to cover much wider geographical boundaries not too long ago. Today, I reside in USA and have not learned of anyone with HV2 mtDNA on 23andMe yet, sure present on other sites but still even more rare in proportion to the population here as well. Their stats show HV2 as 1 in 5000 within 23andMe site for now. The Scythian Ice Maiden is a great finding for sure.
Haplogroup HV is the most successful maternal lineage in Western Europe. Over half of the Western European populations descend from Haplogroup HV. Most Europeans belonging to the HV lineage descend from a branch that was renamed haplogroup H. HV2 is the earliest mutation of HV, and is also My Own Maternal haplogroup. It is the third most common haplogroup among Zoroastrian Parsis of India after U4. My YDNA is I* or the original I, the marker of the ancient Magi or the ancient Zoroastrian priesthood. This is the same Y haplogroup for the ancient Vikings. Today this haplogroup is concentrated highly in Scandinavia and Dinaric Alps. Outside Europe, it appears in northeastern Iran and Indo Iranian population remnants of Turkmenistan, where it most likely has originated. Haplogroup I origins probably go back to the ancient BMAC Culture that is closely associated with ancient Zoroastrianism.
